Go with the Boondocker Box. The other one I believe will only allow you to richen your mixture and would work for pipes I think :dunno: The Boondocker you can lean out or richen at different rpm ranges depending on the mods and the programming. D&D will sell you a box with a starting point for products you buy from them I believe and they offer more rpm ranges in their programming then some of the others.There is more then one program available all within the Boondocker Box but depends who you buy it from I believe but not sure on all the differences.
Hey arctic-kid, You need some terminology for the sleds... :smilielol:
Boondockers- Boondockers are snowmobilers in the mountains that ride off of main trails & in the back woods. They go Boondocking (or riding in the Boondocks, meaning back country).
Boondocker- Boondocker is a company that makes EFI control boxes & Nitrous spray kits for snowmobiles & ATV's.
Highmarking- Mountain riders go up a large hill or mountain at steep inclines. They try to outride each other by making a higher mark on the mountain face with their sled. By going higher than the previous rider, they are highmarking them. ...get it?
That is just some useful terminology for ya. What you are asking about (I think?) is a control box for your EFI (electronic Fuel injected) engine. correct?
IMO (In My Opinion) Boondocker is the best right now. I have it on my sled & it lets me add fuel & air in large quantities...enough for my big bore.
I would go with the Boondocker from D&D they Have There own RPM ranges.
And they will help you out with starting points.
Plus If you would like to add NOS they Have everything you need in stock! :div20:
